Abstract
Medical testing apparatus including a microprocessor controlled centrifuge having a group of cuvettes therein. The apparatus also includes a microdiluter apparatus with a pair of pumps therein of differing diluting capability. The cuvettes have hollow main bodies produced from transparent material to allow analysis of the specimen within the cuvettes by a series of spectrophotometers adapted to read the cuvettes while they are rotating within the centrifuge. Bags of reagent are received within the cuvettes and are designed to burst upon reaching a given level of centrifugal force allowing the reagent to flow from the bags into a test chamber within the cuvette main body. Projections are provided on the cuvettes to control the orientation of the cuvettes when inserted into the microdiluter apparatus. A tab is provided on each cuvette in proper orientation to actuate the appropriate microdiluter pump for the test the cuvette is intended for. The cuvette projections also are coded with a binary code to produce a signal which indicates to the test apparatus which test is being carried out in the cuvette. The apparatus also includes means for receiving the signal from the code reader and from the spectrophotometer and for printing out the test results appropriate for the coding.
